I really appreciate your video, and respect you for sharing it. I'm certain you will get all kinds of responses from people chiming in with their advice or critiques, while they lack the courage to post a video. It is high time that we recognize and expect video to help our analysis, and subject those who refuse to post video to the highest scrutiny.

I have attended Ikeda's seminars before and taken ukemi from him. I think Ikeda is excellent, but I don't perceive anything extraordinary from him. I have never seen him work with non-compliant uke, and I have my doubts as to whether he could accomplish what is shown in the video with uke who are behaving differently.

As for the exercise you are showing, I like it, but I view it as extremely rudimentary.

What do you feel is the benefit of the exercise you have shown in your video? Do you feel that exercise has any carryover to a full intensity attack?

What specific skills are you trying to develop? And how do you think they will enhance your aikido?
